AES Based Steganography

Steganography is the art of hiding the existence of data in another transmission medium to achieve secret communication. It does not replace cryptography but rather boosts the security using its obscurity features. Steganography method used in this paper is based on biometrics and the biometric feature used to implement steganography is skin tone region of images. Here secret data is encrypted by AES (Advanced Encryption Standard) and embedded within skin region of image that will provide an excellent secure location for data hiding. For simplicity and better results this skin tone detection is performed using RGB thresholding technique rather than the HSV (Hue Saturation Value) colour space technique.
